New Ecommerce Store Development Needed

I'm looking to develop a new ecommerce store that mirrors the functionality of my current Big Commerce site but offers a more streamlined process for listing products. The store will focus on selling physical goods and should include specific features to enhance the product listing experience.
Secure site and SEO are priorities.
Key Requirements:
- Develop a user-friendly ecommerce platform for physical goods
- Implement product variation options for colors and sizes
- Ensure a simplified and efficient product listing process
- Integrate secure payment options, including Credit/Debit Card

Ideal Skills and Experience:
- Experience in ecommerce website development
- Proficiency in creating intuitive product management systems
- Knowledge of integrating payment gateways
- Ability to design a responsive and visually appealing online store

I'm eager to collaborate with a skilled developer who can bring this project to life and improve the overall efficiency of my online business.
